SINGEING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,937, dated May 3,1904.

A li tion fil d March 10, 1900. Serial No. 8,141. (No model.)

I0 117/ whom it may concern.

Be it known that I, Max SARFERT, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Singeing-hIachines, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention relates to the art of singeing textile fabrics; and itconsists of a machine for singeing the outside or outer surface ofhollow or tubular articles such, for instance, as hosiery for thepurpose of removing the fuzz, nap, or lint from the outer surface onlythereof, and thus to impart to the article a finished appearance.

My invention further consists of novel details of constructionhereinafter fully described and claimed.

Figure 1 represents a side elevation of a singeing-machine embodying myinvention. Fig. 2 represents a front elevation of Fig. l, a portionthereof being shown in section. Fig. 3 represents a front elevation ofthe burnertubes, showing the air-valve in section. Fig. & represents aplan view of a form to be inserted in the article to hold the same inposition when being singed.

Similarnumerals of reference indicate corresponding parts in thefigures.

For the purpose of illustrating my invention I have shown a machine forsingeing hosiery, as this example best illustrates the principle ofmy'invention, and since my invention has been particularly designed forsingeing hosiery and inaccordance with the broad principle thereof Iemploy two principal instrumentalitiesnamel y, means for supporting thestocking or other article from within and, second, a singeing means,these two means being preferably relatively movable, so as to apply thesingeing means to the outside of the stocking to singe substantially theentire outer surface thereof. It is obvious that these principalinstrumentalities of which my invention consists can be variouslyarranged and organized, and in the accompanying drawings 1 have shownone simple embodiment thereof which I have found in practice to besuccessful and which consists in employing two burners arranged toproject their flames toward each other, a pair of driven rollerssituated next to these burners, so that when a stocking and a formplaced therein to hold said stocking flat is inserted between theserollers said form and surrounding stocking is projected between theburners and the outside of the stocking or its entire outer surface issubjected to the singeing agent, although it is understood that myinvention is not limited to this specific arrangement and organizationof these instrumentalities. I will now proceed to describe the specificconstruction shown in the accompanying drawings.

1 designates the feeding-table, which may, although not necessarily, beemployed and which is supported in any suitable manner in proximity tothe feed-rollers 2. and 3, which are mounted on the shafts L and 5,which revolve in suitable bearings in the framework or housing 6. Theshaft 5 is mounted in stationary bearings, while the shaft A is mountedin boxes or bearings 7, above each of which is a resilient or yieldingcushion 8, upon which rests the plate 9, against which bears the bolt10, which passes through a suitable portion of the housing and is lockedin the desired position by the jam-nut 11. The shaft 4 and thefeed-roller 2 thereon are rotated by any suitable means, as the belt 12and pulley 13,

and power is transmitted from said shaft 4 to the gear 14, which mesheswith the gear 15, mounted on the shaft 5, whereby the latter and itsroller are actuated in unison with the roller 2,, At the discharge sideof the feed- 5 rollers are located the upper and lower burnertubes L6and 1?, respectively, which are supported in. any suitable manner andreceive the gas orvapor from the supply-pipe 0r vaporizer. 18, theadmission of the proper amount 9 of oxygen being regulated by a suitablevalve 19, (seen in Fig. 3,) it being understood that each of theburner-tubes are provided with suitable valves 20 and 21, whereby thesupply of vapor can be readily regulated.

It will be noted that the discharge jets or openings 2). in the upperburner-tube 16 are out of alinement with the jets 23 in the lowerburner-tube and are so arranged that one flame is directed downwardlyand the other upwardly, the downward flame in the present instance beingin advance of the upper flame, whereby the flames are not directed to acommon point, thus minimizing the danger of the flames uniting, and thusburning or scorching the articles passed between them.

In practice I have found it preferable to make the upper burner-tube 16of greater diameter than the lower burner-tube 17, the jetopenings 23-in the latter being of less size than the jet-openings 22, it beingevident, however, that the flame issuing from the ports 23, althoughsmaller than the upper flame, will be equally intense, owing to itsnatural tendency to travel upwardly. 24 designates a receiving-tablewhich may although not necessarily, be employed for the reception of thestocking or other article after 1 being singed.

To support the stocking or other article from within, so that it can bepassed through the machine in a flat condition, I employ a form 25.(Shown in Fig. 4 This form 25 is shown as an ordinary stocking-board,although it is understood that in accordance with my invention the meansfor supporting the stocking within may consist of. any device insertedwithin the stocking to support the same in a flat condition while it isbeing singed. The

stockings are preferably stretched upon this form.

The operation is as follows: The stockings to be singed are supportedfrom within by the form 25, which is so thin that the flames readilyreach those portions of the stocking lying over the edges, as well asthe portions stretched over. the sides of the form,the movement of thegoods being sufliciently rapid to prevent any injurious effects of theflames, and it will be obvious that no singeing action is bad on theinside of the stocking contiguous to said former. The formers and thestockings thereon are propelled in the direction of the arrows seen inFig. l by the feed-rollers 2 and 3, and it will be seen that all thelong surplus fibers or fly will be singed therefrom at one and the sameoperation, which is an important desideratum in this class of work, asit saves much time and labor,and consequently greatly reduces the costof the singeing operation. The upper feed-roller being mounted inyielding or cushioned bearings permits a sufiicient vertical movement tocompensate for the thickness of the form and surrounding the stockingswill be supported in a practically rigid manner during the feeding andsingeing operation.

It will be evident that the feedqollers 2 and 3 can, be duplicatedorarranged in ,pairs in series and the burner-tubes 16 and 17 alsoduplicated without departing from the spirit of myinvention, thefeed-rollers being actuated in unison by any suitable means.

The vapor used in the burner-tubes can be taken from any suitable sourceof supply, and it will be evident that, if desired,thejet-open ings 22and 23 may be made the same size and the inlet to the lower burnertubereduced, which would result in supplying a less quantity of gas to thistube, whereby the size of the flame would be reduced.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
